RADIATOR-VALVE.

Specification of Letters Patent.

' I Patented Oct. 15, 1907.

A'lDllGfiljlOll filed June 17. 1905. Serial No. 265,722.

To whom it may concern:

Be it known that I, GEORGE W. IIAYDEN, a citizen of the United States, residing at Chicago, in the State of Illinois, have invented certain new and useful Improvements in Radiator-Valves, of which the following is a specification.

My invention relates to valves for hot water radiators and other places where a loose fitting and quick opening valve may be used, especially as applied upon bends in the pipe, and more particularly to the mounting of the valve upon its stem, and means for limiting its movement. The objects of the invention are, to provide an improved mounting of a butterfly valve on its stem, and to improve the means for operating it and the stops for limiting its movements, etc., as will hereinafter appear. In the accompanying drawing, I show a preferred form, in which- Figure 1 is a top plan view, and Figure 2 is a side elevation, of an elbow of pipe with my valve applied thereto;

Figure 3 is a vertical central section through the valve casing showing the valve in open position.

The valve is particularlydesigned for an elbow or a curve in the pipe, and it will be seen that in the elbow or casing 4 is provided a fiat sheet metal butterfly valve 5, which is mounted upon the stem 6 and is operated by means of the handle 7 from the outside of the casing. This operating lever 7 has a downwardly extending tail piece 8, which conforms to the curve of the pipe and extends a considerable distance away from the axis of rotation of the valve, and in open position of the valve cooperates with a central stop lug I]. placed upon the casing.

The valve 5 has a pivoting spur 14 at the bottom, seated in the casing. and at the top is provided with a simple notch 13, as shown in Figure 3, which [its in a slit in the end of the valve stem 6, so that the valve has some play in place, and avoids the necessity of nicely adjusting the center 01' the valve and the stem in exact alinement. The pipe 4 has an upwardly extending sleeve 4" on top, which has a packing box 12 for the stem 6, made in any convenient manner. The valve casing also. has the stop lugs 10 on both sides, which cooperate with spur 9 on the valve handle 7, so as to limit the movement when the valve is closed, upon I either one side or the other of the medial line. The handle 7 is placed upon the stem so that it may be changed from one position to the other to operate the valve either left handed or right handed.

It will be seen from this construction that the valve can have some play to fit its position in the pipe, not being rigidly held upon the stem 6; and also that the valve handle 5 may be used either for right hand or left hand to open and close the valve to its normal position. When the valve is to move left handed, as shown in the figures, the lever 7 is mounted upon the stem 6 as shown, and when it is to be used as a right handed valve in other positions, the screw on top of the stem 6 may be removed and this lever 7 set upon the angular shank of the stem in a different position, so as to operate on the other side of the lug 11, in that instance also cooperating with the other stop lug 10 on the valve casing. By reason of the tail 8 of the lever 7 being at a considerable distance away from the axis of the valve, it Will be seen that it may come to practically the same medial position, whether it operates from right or the lelt hand side. Other advantages in the matter of simplicity of design will readily occur to those familiar with such devices.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is the following:

1. A radiator valve comprising in combination a casing with a passage therethrough, a valve stem. and a butterfly valve in the passage connected with such stem by a loose spliced joint adapted to permit of lateral play by the valve in its own plane.

2. A radiator valve comprising in combination a casing with a passage therethrough, a valve stem, a butter-fly valve in the passage connected with such stem by a loose spliced joint adapted to permit of lateral play by the "alve in its own plane, and having a projection l-L opposite said spliced joint, and a recess in said casing receiving said projection.

A radiator valve comprising in combination a casing with a passage therethrough, a valve stem having a slot in its end. and a butter fly valve in the passage having a slot in its edge, the stern and valve inter-fitting into each other loosely at the said slots in the respective parts to permit of lateral play of the valve in its own plane.

4. In a radiator valve, the combination of a valve casing with a passage therethrough, a valve stem, a butterfly valve in the passage connected with such stem by a loose spliced joint adapted to permit of lateral play by the valve in its own plane, a long handle crznnected to the valve stem and a stop on the center line of the casing in position to engage the end of the handle.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.

GEORGE W. HAYDEN.
